Answer 1

试试这个(这是一个日期时间扩展)。所以用法是:

var date = new DateTime.Now;

string formattedDate = date.ToReadableTimespan();


public static string ToReadableTimespan(this DateTime d)
            {
                // 1.
                // Get time span elapsed since the date.
                TimeSpan s = DateTime.Now.Subtract(d);

                // 2.
                // Get total number of days elapsed.
                int dayDiff = (int)s.TotalDays;

                // 3.
                // Get total number of seconds elapsed.
                int secDiff = (int)s.TotalSeconds;

                // 4.
                // Don't allow out of range values.
                if (dayDiff < 0 || dayDiff >= 31)
                {
                    return null;
                }

                // 5.
                // Handle same-day times.
                if (dayDiff == 0)
                {
                    // A.
                    // Less than one minute ago.
                    if (secDiff < 60)
                    {
                        return "just now";
                    }
                    // B.
                    // Less than 2 minutes ago.
                    if (secDiff < 120)
                    {
                        return "1 minute ago";
                    }
                    // C.
                    // Less than one hour ago.
                    if (secDiff < 3600)
                    {
                        return string.Format("{0} minutes ago",
                            Math.Floor((double)secDiff / 60));
                    }
                    // D.
                    // Less than 2 hours ago.
                    if (secDiff < 7200)
                    {
                        return "1 hour ago";
                    }
                    // E.
                    // Less than one day ago.
                    if (secDiff < 86400)
                    {
                        return string.Format("{0} hours ago",
                            Math.Floor((double)secDiff / 3600));
                    }
                }
                // 6.
                // Handle previous days.
                if (dayDiff == 1)
                {
                    return "yesterday";
                }
                if (dayDiff < 7)
                {
                    return string.Format("{0} days ago",
                        dayDiff);
                }
                if (dayDiff < 31)
                {
                    return string.Format("{0} weeks ago",
                        Math.Ceiling((double)dayDiff / 7));
                }
                return null;
            }
